Some Question's from my side :

CPU :

Xeon gaming and normal apps - How is Xeon on Gaming and Normal PC applications?
i7 Extreme Sandy Bridge - Is this required for my usage and will it be worth it?
Core i7 First Gen Core systems - So Sandy Bridge Extreme Processors are very expensive but 970 and 980 6 core Westmere CPU's cost only $500.Is that a bargain and Is buying 1 year old processors good?

i7 2600K - Will this be enought for me?
i5 2500K - Will this be enought for me?

Core vs thread - so AMD vs Intel,AMD provides more Cores but Intel does threading.Whats the difference?
Duration Without Update - How long each of them will be enough to perform the heavy task applications,2-3 years?

Motherboard :

Sound Card - Is it Required or Motherboard will take care of it
Wi-Fi Card - Is it Required or Motherboard will take care of it
Blue-tooth Card - Is it Required or Motherboard will take care of it
SATA 3 and PCI-E 3
Duration Without Update - How long will this be enough to perform the heavy task applications,2-3 years?

RAM :

Channels - How many channels is good?
Speed - Whats the difference between different 'mhz'?
Duratin Without Update - How long will this be enough to perform the heavy task applications,2-3 years?

GPU:

Cores - I read this when checking out Nvidia Cards,they have 100's of cores.What do they mean?
Speed - How much is good as in 'hz'?
Bandwidth - How much bandwidth is good?
Duration Without Update - How long will latest GPU's be enough to perform the heavy task applications,2-3 years?

Display:

What Aspect ratio should the Display have as WEB is designed 4:3 and many movies have 21:9 ratio.
Do the multidisplays connection to GPU share resolution in output of do they have 2 x resolutions coming out of GPU?

Heatsinks and Coolers:

Are liquid Coolers really required?
Fans vs Liquid Coolers?
Are heatsinks required?
What all components can and should have heatsinks and cooler?I see them on RAM these days

Wireless :

Wireless Headphones,Keyboard,Mouse,Router - What does range in 'HZ' mean
Will different wireless technologies interfere with each other?

Speakers and Headphones - Standard - What do different Standards like dolby,true HD differ?
Power Supply - How Many Watts Should my Power Supply be and what all Sockets Should it have?
Keyboard - Do i need to my two keyboards? Ergonomic keyboards for typing and SonyApple Wireless keyboard or just one?

Please Help in the following way:

Technology - As in what all tech is needed to make it possible like technical information like cores,wi-fi,pci express,aspect ratio,memory,etc

Products - Products on the market that will make it all possible like Intel,Nvidia,Evga,Asus,Apple,Cisco,etc and their different product lineup's.

Suggestions - Suggest what configurations will be good for my usage like xeon,core i extreme,core i7,12gb ram,etc

best is go with
core i5 processor
nvidia graphic card
7.1 channel sound card
pci express slots
4 GB DDR3 RAM with more ports to expand it in future
HDD so can go with 750 GB or 500 GB whichever u feel better

If you like can go with liquid cooling technology it will give your CPU superb look

Go with Core i7 if ur searching for powerful PC.
